25.6.3 Link Monitoring Commands
This table lists the commands for link monitoring. Link monitoring has the master ZyWALL shut
down all of its VRRP interfaces if one of its VRRP interface links goes down. This way the backup
ZyWALL takes over all of the master ZyWALL’s functions.
[no] device-ha sync port <1..65535> Specifies the port number to use to synchronize with the specified
ZyWALL router. The
no command resets the port to 21.
[no] device-ha sync authentication
password password
Specifies the password to use when synchronizing. Every router in the
virtual router should use the same password. The
no command resets
the password to “1234”.
password: You can use 4-63 alphanumeric characters, underscores (_),
dashes (-), and
#%^*={}:,.~ characters.
[no] device-ha sync auto Specifies whether or not to automatically synchronize at regular
intervals.
[no] device-ha sync interval <5..1440> Specifies the number of minutes between each synchronization if the
ZyWALL automatically synchronizes with the specified ZyWALL router.
The
no command resets the interval to five minutes.
[no] device-ha sync now Synchronize now.
